The families of ousted president Mohamed Morsi's presidential team who have been detained in undisclosed locations since 3 July issued a statement Wednesday demanding their immediate release.

"What members of the presidential team have been facing [in] fabricated charges is a disgrace for their abductors who once swore to respect the constitution," read the statement presented by the families at a press conference earlier Wednesday at the Lawyers' Syndicate.

"The members of the presidential team have been defamed in the media with no chance to defend themselves," the statement continued, adding that families have had no contact with presidential team members.Members of Morsi's presidential team and aides detained include Essam Haddad, Morsi's aide for foreign affairs, Rafaa El-Tahtawi, presidential chief-of-staff, and Ayman Ali, presidential advisor for media.

Four members of the six detained are currently  facing investigations into clashes at Ittihadiya presidential palace in December 2012 between Morsi supporters and opponents.

The families also announced at the press conference that they are going to sue "the coup authorities" responsible for the "abduction" of presidential team members.

On Sunday, prosecutors decided to legally detain El-Tahtawi and Asaad Sheikha, Morsi's former deputy chief-of-staff, for 15 days pending investigations into their involvement in the Ittihadiya clashes.

On Tuesday, prosecutors alsodecided to legally detain Ahmed Abdel-Ati, Morsi's ex-presidential office manager, and Ayman Hodhod, Morsi's ex-advisor for safety and crises management, for 15 days on similar charges.
